Sampling
Probability Sampling, a technique in which every unit in the population has a chance of being selected in the sample, and this chance can be accurately determined.
Simple random sampling, all possible subsets of a population are given an equal probability of being selected.
Systematic Sampling, the sampling frame is ordered according to some criteria and elements are selected at regular intervals through that ordered list.
Stratified Sampling, the sampling frame is divided into homogenous and non-overlapping subgroups and a simple random sample is drawn within each subgroup.
Cluster Sampling, a sampling plan used when mutually homogenous yet internally heterogeneous groupings are evident in a statistical population.
Matched Pair Sampling, for comparing two subgroups pithing one population based on s specific criterion.
Multi-stage sampling, combingation of sing-stage sampling techniques.
Non-probability Sampling, a sampling technique in which some units od the population have zero chance of selection or where the probability of selection can not be accurately determined.
